CARR, DECEASED, ASSIGNOR, BY MESNE ASSIGNMENTS, TO UNITED-CARR FASTENER CORPORATION, OF CAMBRIDGE, MASSACHUSETTS, A CORPORATION OF- mnssacnusnrrs TRIMMING INSTALLATION Application filed February 26, 1925. Serial No. 11,696.

g This invention aims to provide an improved trim strip installation and an improved fastener primarily, though not exclusively, useful in connection with such installation.

Reference is made to a division of this application, Serial No. 52,318, filed August 25th, 1925.

In the drawings, which illustrate a preferred embodiment of my invention:

Figure 1 is an elevation view of a window and window frame portion of a vehicle body showing one use of my invention;

Fig. 2 is a section on the line 2-2 of Fig. 1,-showing the trim strip secured'to the window frame bystud and socket means;

Fig. 3 is a section of the trim'strip showing the stud parts of a separable fastener be-.

ing secured thereto;

Fig. 4 is a fragmentary elevation view of a portion of the trim strip showing the stud elements secured thereto;

Fig. 5 includes a plan and a side elevation of the attaching part of a fastener stud; and Fig. 6 includes a plan and a side elevation of the socket-engaging part of a fastener stud.

Referring tothe drawings, I have shown one of the uses of a quick detachable trimming strip. The trimming installation includes a body part 1, which may be the body of an automobile, an upholstery fabric 2 covering portions of the inside of the body and a .wooden trim strip 3 secured to the body 1 by a plurality of separable stud and socket fastening elements. All the above mentioned parts except the stud elements are substantially as shown' and more fully described in my copending application 'Serial No. 11,695, filed herewith.

The stud elements as illustrated include a socket-engaging part 4 and an attaching.

plate 5. The socket-engaging part .has a head 6, a neck 7 and a reinforced base portion 8, and is provided with slots 9"which extend from the top of the head into the base 8 (Fig. 6) to permit contraction and expansion of the head 6. The base portion has its edge turned back upon itself to add strength thereto to prevent the base portion from splitting ad- 'jacent the slots 9. The attaching plate 4 is formed from a single piece of metal and is preferably rectangular, having its corner por- To assemble the studs with the wooden strip 3, I first drill two concentric recesses in the strip 3 at the inner face thereof. The smaller recess 11 receives the base 8- of the socketengaging part 4 and the larger recess receives the attaching plate 5. First the stud is placed in the recess 11 and the attaching plate is then placed over the head 6 and neck 7 of the stud, as best illustrated in Fig. 3. I prefer to have the head of the stud snap through the aperture in the attaching plate as an initial means of assembling the stud. element. The neck of the stud is therefore made sufficiently small enough in diameter so that the stud may shift pressed into place, as illustrated in 2.

A suitable tool 13 (Fig. 3) then presses the plate 5 toward the base 8 of the stud, thereby flattening the corners of the plate and forcing them into the wall surrounding the recess 12 as shown in Fig. 2. Thus the plate 5 is countersunk into the strip 3 to hold the socket-engaging part 4 in assembled relation therewith so that only the head and neck of each stud extends beyond the inner face of the strip.

The base 8 of the socket-engaging part 4 is of a smaller diameter than the diameter of.

its recess 11 and the aperture 10 in the attaching plate is larger than the-diameter of theneck of the stud, thereby permitting lateral shifting of the stud relative to the attaching plate 5 and the trim strip 3 for alignment with a stud-receiving aperture 14 presented by the body part 1.

By securing the stud members to the strip in the above-mentioned manner, the strip may fit tightly against the upholstery fabric 2 and the frame 1 to provide a finished edge.

I have found that trim strips secured to the frame parts of the car by stud and socket ele- .ments hold very firmly when applied and may be easily and quickly removed for access to mechanical parts of the car underlying the upholstery.

While I have shown and described a preferred embodiment of my invention, it will be understood that changes involving omission, substitution, alteration and reversal of part presenting a stud-receiving means,

frame covering means presenting at the inner face thereof a stud member having a yieldable head engaged with said stud-receiving means thereby securing said frame covering means to said frame and'a washerlike plate engaging said frame covering means thereby holding said stud in position and said plate having an aperture through which-the yieldable stud head passes, said aperture being smaller in diameter than the largest diameter of said head so that the washer is snapped over the head of the stud and said frame covering means having an aperture of greater diameter than that portion of the stud located therein whereby said stud may shift in any lateral direction relative to said frame covering means.

2. A quick detachable trimming strip comprising, in combination, a trimming material having a recessformed therein at the inner face thereof, a stud having a head, aneck and a base portion, said base portion being 10- cated in the said recess in said trimming material, and a relatively flat plate extending over said base and having means embedded in 'said trimming material to secure said stud thereto, said stud head passing through an opening in said plate, and said opening and said recess being large enough to permit lateral shifting of the stud member relative to the trimming material.

3. A fastener secured installation comprising, in combination, a frame having studreceiving means, frame covering means secured to said frame by snap fastener studs having heads engaged with said stud-receivmg means, said studs having bases located in recesses in said frame covering means and attaching means secured to said frame covering means and providing means holding said studs in assembly therewith thereby providing a quick detachable covering means, and said frame covering means being. rigid and imperforate at the exposed side. 4. A fastener secured installation comprismg, in combination, a frame having stud-receivmg means, frame covering means secured to said frame by snap fastener studs having heads engaged with said stud-receiving means, said studs having bases located in recesses in said frame covering means and attaching means secured to said frame covering imperforate at the exposed side' and means providing a lost motion connection for permitting lateral shifting movement of the studs in any direction relative to'the frame covering means. f I

5. A trimming installation comprising, in combination, a frame part presentinga plurality of snap fastener receiving elements, a trimming strip made entirely of rigid material and presenting a plurality of snap fastener stud elements cooperating with said first-mentioned fastener elements to secure said trimming strip to said frame and attaching means securing said fastener elements to said trimming strip, said attaching means being located entirely at the inner face of said trimming strip whereby said trimming strip is imperforate at the outer face and means providing a lost motion connection whereby one of said fastener elements is freely shiftable in any lateral direction relative to its cooperating fastener element to permit alignment and engagement of said fastener elements.
